Hey there, I picked up a DIY telecaster off Reverb and I love it. It's my first Telecaster, but it won't be my last--it's cool to have such a variety of tones available and the thing feels great to play. When I got it, the intonation was perfect up and down the neck. Then I replaced the strings. I guess it came with 9s, because the new 10s have a touch more tension. And now the intonation is... different. It's great up through the 12th fret, but higher than that, everything goes increasingly sharp. What's the cause? How can I get it back? (I haven't tinkered with my guitars much, but I have some tools and mechanical skills from bicycles and computers.) I have this GFS bridge and GFS locking tuners. Thanks!
